Malpaís de Güímar

The large cone is called Montaña Grande (Big Mountain) and reaches a height of 276 m (906 ft).

The Malpaís de Güímar were formed by a series of volcanic eruptions, the most recent and most evident occurring from fissures in the side of the Montaña Grande cone less than 10,000 years ago.

Two peaks from former eruptions stand above the lava plain, Montaña de la Mar ("Mountain of the Sea") and Las Morras del Corcho ("Cork Bluff").

In addition to aa lava flows, there have been pyroclastic eruptions of ash and volcanic bombs that formed the various cones.

Notable is Cueva Honda ("Deep Cave"), which was formed by a large gas bubble within a lava tube.
